Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides hard shell sports shoes made of plastic acid;
More typically, it relates to alpine ski shoes.

In particular, the present invention provides a ski binding that satisfies certain international standard criteria defined to ensure a good safety function of the binding that constitutes the functional interface between the shoe and the ski. The target ski boots have soles that allow them to be stored in the shoe and also be used for walking.

The popularity of alpine skiing has increased the number of skiers and with it the problem of adapting shoes to the shape of their legs so that they can ski with maximum safety and comfort. has also woken up. Further, the problem of fixing the angle depending on the orientation of the shape of the skier's legs is a subject of technological development. One such technological development concerns a means of orienting the foot by changing the orientation of the upper relative to the surface of the ski, as disclosed in U.S. Pat. Nos. 3,922,800 and 374.
No. 7235, No. 3885329 and French Patent No. 2
This is clarified by the mechanism described in each specification of No. 166677.

Still other documents teach how to fix the angle of the shoe at the sole by adding a wedge. U.S. Pat. No. 4,078,322 discloses that the different play of the sole section provides different cant angles for the same boot shell that can always be used in conventional bindings. A ski boot with a removable and replaceable built-in sole is specifically mentioned.

In fact, in U.S. Pat. No. 4,078,322, the cant angle of the shoe can be changed at a retail store according to a predetermined range of inclination angles, or the skier himself can have it as a replacement part. However, these sole parts are not always readily available to skiers. On the other hand, if a skier decides to change the corresponding sole between his right shoe and his left shoe, he will automatically switch from the outside of his knee to the inside, or On the contrary, the cant angle (wedge fixing inclination angle) is changed, which, instead of solving the problem of adapting the shoe to the shape of the leg, may even make it worse.

The present invention allows the right and left soles of a pair of shoes to be interchanged so as to change only the amount of cant within the morphological orientation given to each of the skier's legs. Accordingly, it is proposed to improve the canting device of ski boots by means of a removable sole part.

Therefore, for this purpose one invention provides a removable sole part or an adapter for the sole, which can be a single unitary unit over the entire length of the sole, but alternatively can preferably be separated into two parts. Alpine ski boot having a wedge-fixing cant consisting of a recess or cutout suitable for accommodating the adapter and oriented at an angle to the surface with which the adapter contacts the ground. It is. This oriented recess is of a shape suitable for constituting a means for cooperating with a retention means arranged in the lower shell of the ski boot and comprising a projection correspondingly shaped to the recess of the adapter. It has become.

The sports shoe which is the object of the invention thus comprises a rigid sole adapter, the lower part of which is removable with respect to the shell sole for cooperating with the fastening means on the ski. The shoe sole adapter has a shell;
creating a cant of the shoe relative to the surface of the ski according to a predetermined angle, while the lower part of the hard shell of the boot is oriented according to an arbitrary directional angle α relative to the general plane of the shell. The sole adapter includes a holding means for a sole adapter, and the sole adapter is oriented according to a cant angle β with respect to the contact surface of the sweep plate and the adapter, which is different from the directional angle α. Its main feature is that it includes complementary means of cooperation.

According to another feature of the invention, the hard shell ski boot includes an adapter interchangeable between the right and left feet of a pair of shoes.

Finally, other characteristics and advantages of the invention will become apparent from the non-restrictive exemplary embodiments shown in the accompanying drawings and the description below.

FIG. 1 shows a ski boot l placed on a ski 2, the upper surface of which has an overall wedge-fixed inclination angle (cant angle) obtained by the structural arrangement of the invention. )
It serves as a reference surface for measuring.

This ski boot l consists of a rigid shell 3 on which is mounted a torso 4 hinged along an axis 5, and
It includes a sole 6 for reliable cooperation with bindings (not shown here) on the ski 2 during walking.

Advantageously, this sole 6 is provided with at least one sole adapter 6' which is removable from the lower part of the shell;
It is fixed using cooperating means 7 reinforced by additional assembly means such as screws or rivets.

Furthermore, the hard shell 3 is provided in its lower part with a holding stage for accommodating cooperating means 7 arranged on the sole adapter (FIGS. 2 and 3). These retaining means are constituted by slider-type tenons 8 and 9, respectively, in the front and heel parts of the shell base, above which, in accordance with one of the characteristics of the invention, there is a corresponding toe. Part 6
' and heel part 6'' (indicated by dotted lines) are fitted. The shell 3 is oriented at an angle α to the axis of the hinge connection rivet 5 to the horizontal line and as shown in FIG. The slider type groove 8.9 is wedge-fixed at a direction angle α to the vertical line of the plane containing the lower surface of the shoe so that it is directed outward for the shoe of the right foot.In this way, it is mounted on the shell. The hinged torso 4 for the shoes is pre-wedged outwardly at a predetermined angle α according to a preferred embodiment, the directional angle α being approximately 2 outwardly for each pair of shoes. °30'. Of course, this direction angle can also be inclined inward. □ Figure 4 shows an adapter for a pair of toe parts 6', and Figure 4a shows the toe of the left foot. part adapter, and also part 4b.
The figure shows the adapter for the toe of the right foot. Each adapter
6' is at least partially provided with a non-slip textured walking surface lO and is located within the standardized thickness of the adapter and corresponds to and complements the shape and dimensions of the slider type groove 8.9. It is provided with a hollow part 11 having a shape and dimensions. This hollow part 11 has an arbitrary wedge fixing angle (cant angle) oriented toward the outside of the shoe, for example, with respect to the walking surface.
It is sloped at β.

Figures 5a and 5b show the application of the invention to the shell of a pair of ski boots fitted with a removable adapter. The attached assembly ensures adjustment of the lateral inclination angle of the shoe slanted outwards along the overall wedge fixation inclination angle (cant angle) γ. This overall wedge fixed inclination angle (cant angle) γ is determined by the hard shell 3 oriented outwardly by the direction angle α and the cant angle β
an adapter 6' for a shoe sole including a hollow part 11 provided with a
Obtained by combining with 6''.

By way of example, assembly of such a shoe is realized by means of a shell 3 in which a slider-type tenon 8 is fitted into the hollow part 11 of the adapter 6' as described above. Since each member thus attached and assembled is given angles α and β, the overall cant angle γ
The values of correspond to the algebraic flaws of the values of these angles α and β.

Therefore, for a shell 3 which is angled at, for example, 2°30' with respect to the plane of the holding means constituted by the slider grooves 8 and 9, the hollow portion 11 constituting the cooperating means will be at an angle of O"30'. , and an adapter for the sole provided with an angle of 1'30'.For the same pair of shoes, these angles are configured to be symmetrical, and the value of the angle β is f The overall cant angle γ is configured to be different from the value of the angle α depending on the case shown in the diagram. (Fig. 6).Therefore, the adjustment range of the lateral inclination angle for the same pair of shoes is given in the table below, defined by the limit values γl to γ2. As expected.

Therefore, thanks to the device according to the invention, a skier with an outwardly curved leg (leg 0) can always have its lateral wedge fixation in the position of the varus layer or for a value of an angle different from the above-mentioned angle. It can be seen that the value of the inclination angle (cant angle) can be adjusted.

Of course, skiers with genu valgum (inwardly curved legs)
Also, by keeping the lateral inclination direction angle α towards the outside of the shoe with a value β of the cant angle of the adapter greater than the value of α, or alternatively by maintaining a value β of the cant angle of the adapter smaller than the value α. Therefore, adjustment can be made in the same way by giving an inclination direction angle α toward the inside of the shoe. In order to perfectly hold the adapter against the slider type groove on the shell, an assembly method that does not require disassembly is required to prevent the adapter from coming off the slider at the bottom of the shell. Provided at each adapter location. In this way, the seventh

shown inside. This adapter 6' has an overall cant angle γ obtained in the walking surface area lO depending on whether it is attached to the left shoe or the right shoe.
It includes marking marks 13 indicating the direction and value of. As an added bonus, this marking is placed in a non-slip textured recess on each adapter to prevent it from becoming difficult to read due to walking surface wear. The various descriptions set out by reference in FIGS. 1 to 7a above illustrate the various possibilities of arrangement and use of the device according to the invention, as well as other embodiments and existing uses that do not depart from the scope of the invention. It defines the law.
